Actually I'm quite sure you can have the same address for BCH and BTC as long as you add the private key to the wallet. Otherwise no one would have been able to get their BCH from the initial Bitcoin Cash split ( or Airdrop or whatever it is called ).

If it is a limitation of zpool that I can not change it that would be another matter. If so I guess I will just stick with this address until a BCH payout happens and create a new address at that time.

Hi
I just started mining to zpool and initiallly set BCH as my payout coin. But I started seeing this message:

We are short of this currency (5.69940404 BCH). Please STOP your miners and switch to BTC until we find more BCH blocks.
YOU are responsible if you continue to mine for BCH despite this warning.

So I switched the password to c=BTC, but 20 hours later and I'm still getting the message, even though furter down on the wallet page I can see:

Details	Extra	Algo	Diff	ES**	Hashrate*
cgminer/4.8.0	c=BTC	sha256	32768	3.4	TH/s

Is there anything further that I'm supposed  to do to switch to BTC?
